Definitions

  • This invention relates to an information processing apparatus such as a personal computer or a word processor. More specifically, this invention relates to a thin, light-weight information processing apparatus having speakers.
  • An example of conventionally known information processing apparatuses according to the prior art with built-in type speakers includes a pair of speakers provided at respective side surfaces of the main body of the apparatus.
  • the speakers of this apparatus are fitted in such a fashion that their sound radiation surfaces (or their fitting surfaces) are parallel respective side surfaces of the main body of the information processing apparatus.
  • the thickness of the information processing apparatus is limited by the height of the sound radiation surfaces of the speakers, and the thickness cannot be reduced so easily.
  • a pair of speakers is disposed on respective sides of the rear part of the upper surface (the surface on which an operation surface is positioned) of the apparatus main body.
  • the speakers are disposed in such a manner that their sound radiation surfaces are parallel to the upper surface, i.e., the operation surface, of the apparatus main body. That is, the sound radiation surfaces of the speakers exist on the projection surface of the information processing apparatus.
  • the speaker surfaces cannot be secured in relation with the area of the operation surface, and speakers having sufficient sizes cannot be mounted.
  • the speakers are allowed to swell out from respective sides surfaces of the main body of the information processing apparatus when they are used.
  • the speakers are fitted so that their sound radiation surfaces are situated on the upper surface of the swelling portions. Because the speakers 2 are allowed to swell out from the apparatus main body 1 during use, however, the swelling portions are cumbersome, and remarkably impede portability of the information processing apparatus.
  • Japanese Unexamined Patent Publication (Kokai) No. 8-76885 describes an example wherein the speakers are disposed on a peripheral processing substrate, disposed separately from a main substrate, in order to reduce the thickness of the apparatus main body in an information processing apparatus having speakers.
  • an information processing apparatus having at least one speaker, said apparatus comprising: a body of said information processing apparatus, said body having a reference surface thereof; and said speaker having a sound radiation surface which is oblique with respect to said reference surface of the body.
  • an information processing apparatus having at least a pair of speakers, said apparatus comprising: a body of said information processing apparatus, said body having a reference surface and respective left and right sides thereof; and said pair of speakers arranged at said left and right sides, respectively, each of said speakers having a sound radiation surface which is oblique with respect to said reference surface of the body.
  • an information processing apparatus having at least a pair of speakers, said apparatus comprising: a body of said information processing apparatus, said body having a reference surface thereof; and an extended station on which said body is detachably mounted and said extended station having left and right sides thereof; and said pair of speakers arranged at said left and right sides, respectively, each of said speaker having a sound radiation surface, in such a manner that said sound radiation surface is oblique with respect to said reference surface of the body; and said extended station having respective gaps, each of which is defined at a front part of said sound radiation surfaces of the respective speaker, when said body is mounted on said extended station.
  • an information processing apparatus having at least a pair of speakers, said apparatus comprising: a body of said information processing apparatus, said body having a reference surface thereof and provided with a keyboard section; a display section; said body having a shaft to which said display section is pivotably connected; said display section being constituted as a lid portion for said body; said pair of speakers arranged at said left and right sides, respectively, and each of said speakers having a sound radiation surface which is oblique with respect to said reference surface of the body.
  • the height can be remarkably reduced and the apparatus main body can be made far thinner than when the speakers are fitted to the side surfaces of the information processing apparatus. Further, the installation area of the speakers on the projection plane can be reduced in comparison with the case where the speakers are disposed so that their sound radiation surfaces exist on the projection plane of the information processing apparatus main body, and the areas of the sound radiation surfaces of the speakers can be sufficiently secured.
  • a gap is defined at the front part of each of the sound radiation surfaces of the speakers. According to this arrangement, the gap portions at the front surface portions of the speakers serve as sound diffusion areas and a sound quality of the speakers can be improved.
  • FIG. 1 ( a ) is a perspective view of an information processing apparatus having speakers of this invention according to the first embodiment of the invention.
  • FIG. 1 ( b ) is an enlarged sectional view of a portion A in FIG. 1 ( a );
  • FIG. 2 ( a ) is a perspective view of an information processing apparatus having speakers of this invention according to the second embodiment, and FIGS. 2 ( b ) and 2 ( c ) are enlarged sectional views of a portion B in FIG. 2 ( a );

  • FIGS. 2 ( b ) and 2 ( c ) are detailed sectional views of portion B in FIG. 2 ( a ). As shown in these drawings, the speaker 2 is fitted to the slope surface of this notch portion 5 at a fixed relationship.
  • the speaker 2 is fitted on the lower surface of, and inside, this notch portion 5 in such a manner as to incline progressively downwardly towards the side edge of the main body 1 and mounted to the body 1 so as to be immobile with respect to the body 1 .
  • the gap (notch portion) 5 exists in front of the sound radiation surface 2 ′ of the speaker 2 , and this gap 5 has across-sectional area which progressively increases towards the side edge of the main body 1 of the information processing apparatus, and defines the sound diffusion area from the speaker 2 . In this way, the tone quality of the speaker 2 can be improved.
  • FIGS. 3 ( a ) and 3 ( b ) show another embodiment wherein the speakers are not provided on the main body 1 of the information processing apparatus, but are fitted to an extended (docking) station 10 , and so a to be immobile relatively thereto, to which the main body 1 of the information processing apparatus can be removably fitted.
  • FIG. 3 ( a ) shows a state before the main body 1 is loaded to the station and
  • FIG. 3 ( b ) shows a state after the main body 1 is loaded to the extended station 10 .
  • Both of the drawings are perspective views.
  • the information processing apparatus per se, which can be loaded to the extended station 10 , is well known. Generally, when the main body 1 of the information processing apparatus is loaded to the extended station 10 , their connectors (not shown) are mutually fitted, and the main body 1 of the information processing apparatus and the extended station 10 are electrically connected with each other.
  • both front and rear sides of the extended station 10 somewhat protrude from the main body 1 of the information processing apparatus as shown in FIG. 3 ( b ) but their side portions are superposed with one another.
  • notch portions 11 are defined at respective side positions, disposed toward the front part of the upper surface of the extended station 10 in such a manner that they incline progressively downwardly towards the right and left sides and the upper side of the extended station 10 is open, and the speakers 2 are fitted into the notch portions 11 , respectively. Therefore, the sound radiation surface of each speaker 2 inclines progressively downward towards the side edge of the extended station 10 .
  • the gap (notch portion) 11 the sectional area of which progressively expands in a direction towards the side end of the extended station 10 , is defined in front of each speaker 2 in the same way as in the embodiment shown in FIG. 2 wherein the bottom surface of the main body 1 of the information processing apparatus closes the open surface of the notch 11 .
  • This gap 11 defines the sound diffusion area from the speaker 2 in the same way as in the embodiment shown in FIG. 2, and sound quality of the sound generated from the speaker 2 can be improved.
  • FIGS. 4 to 6 show the change of dimension when the speakers are disposed obliquely.
  • FIG. 4 shows the case where the speaker 2 is fitted in parallel to the side surface of the main body 1 of the information processing apparatus on the right side (prior art example) and the speaker 2 is fitted obliquely at an angle, ⁇ with reference to the reference surface (operation surface as the horizontal plane) of the main body 1 on the left side (this invention).
  • symbol ⁇ h represents the decrement in the direction of thickness.
  • the speaker has an outer diameter r 1 , a thickness D 1 at the center and a thickness D 2 at an outer peripheral portion.
  • FIG. 5 ( a ) shows the case where the speaker 2 is brought into contact with the main body portion 1 of the information processing apparatus, at its thickness portion (D 2 ), when it is disposed obliquely with the sound radiation surface thereof facing up
  • FIG. 5 ( b ) shows the case where it is brought into contact with the main body portion ( 1 ) of the information processing apparatus, at the thickness portion (D 1 ) at the center when the speaker 2 is disposed obliquely with the sound radiation surface thereof facing up.
  • the ⁇ h value is different, depending on the shape of the speaker 2 , that is, the outer diameter r 1 of the speaker, the thickness D 1 at the center portion, the thickness D 2 at the peripheral portion, the diameter at the center portion etc., but in all the embodiments, the size in the direction of height can be reduced by maximum ⁇ h.
  • FIG. 6 shows the case where the speaker 2 is fitted to the upper surface, at which the operation surface of the information processing apparatus main body 1 exists (prior art example) and the speaker 2 is fitted obliquely at an angle ⁇ with respect to the reference surface of the information processing apparatus main body 1 on the up side (this invention).
  • symbol ⁇ w represents the decrement in the direction of the plane, and this ⁇ w is given by the following equation:
  • the installation area of the speaker 2 can be reduced by a maximum of ⁇ w in the planar direction without being much affected by the shape of the speaker 2 . Therefore, the dimension of the information processing apparatus main body 1 itself can be reduced by maximum ⁇ w on the right and left sides, too.
  • FIG. 7 is a perspective view of the information processing apparatus main body 1 , the add-in battery 8 and the extended (docking) station 10 having the speakers 2 accommodated and mounted therein in the same way as in the embodiment shown in FIG. 3 .
  • FIG. 8 is a perspective view showing the state where the add-in battery 8 is loaded to the information processing apparatus main body 1
  • FIG. 9 is a perspective view showing testate where they are further loaded to the extended station 10 .
  • the add-in battery 8 can be removably fitted to the information processing apparatus 1 as described above. According to the present invention, however, the add-in battery 8 can be further loaded to the extended station while it is kept loaded to the information processing apparatus main body 1 . Therefore, the extended station 10 is provided with a recess 14 for accepting the add-in battery 8 . Since this recess 14 is not a mere opening but is a recess, a wiring pattern such as a printed board for supplying and transmitting power and signals between regions at the front and back of the extended station can be disposed below this recess 14 and the space can be therefore utilized effectively.
  • the connector (not shown) disposed on the back surface of the information processing apparatus main body fits to the connector of the extended station 10 and establishes the electrical connection between them.
  • the speakers 2 are disposed on front portions of respective sides of the extended station 10 . These speakers are inclined downwardly towards the respective side edges. Therefore, thin speakers 2 can be effectively disposed.
  • the back surface of the information processing apparatus main body 1 keeps contact with the upper surface 12 of the extended station 10 under the state where the information processing apparatus main body 1 is loaded. Because the speakers 2 on both sides are inclined, however, the gaps are defined between the speakers 2 and the back (i.e., bottom) surface of the information processing apparatus main body, and the speaker sound can be effectively diffused.
  • the speakers are fitted in such a manner that their sound radiation surfaces are inclined in fixed relationship relatively to a main surface of the body 1 with respect to the reference surface of the main body of the information processing apparatus. Therefore, in comparison with the case where the speakers are merely fitted to the side surfaces of the information processing apparatus, the height can be reduced, and the thickness of the apparatus main body can be reduced. Further, the installation area of the speakers on the projection surface can be reduced and the area for the speaker surface can be sufficiently secured in comparison with the case where the speakers are disposed so that their sound radiation surfaces exist on the projection surface of the information processing apparatus main body.
  • the gap is formed in front of the sound radiation surface of each speaker, the gap portion of the front surface of each speaker serves as a sound diffusion area, and tone quality of the speaker can be improved.
